Remixed it from Spammers and TomusC for the Ender-3 (non-Pro).
So this design will not fit on a Meanwell power supply.
Used only the tray from TomusC.

1-1-2019 Changed width of tray to 5 cm and length to 11.4 cm and filled the redundant nozzle holders. Changed the end of the tray to make it fit around the PSU and before the frame bar. Printed a copy myself to check adjustment needs.
2-1-2019 Lowered fan-side of the tray to prevent blocking of the fan and straytend the tools tower.
3-1-2019 Created a low tray next to the nozzle holders for little tools, prints or SD-cards
5-1-2019 Moved the tools block more to the right side and cut some from the left side away to make sure the fan of the PSU is free. Discovered an error in my last print and corrected it by adding some filling to the back of the tool block. As far as i am concerned this project is finished. I hope to see some great comments and makes from you !
19-2-2019 Uploaded a new version with better numbers on top, hope you like it.
22-2-2019 Uploaded a small revision so the numbers do not have lines around them
6-4-2019 Another revision because there were some leftovers from the old numbering inside the design
2-5-2019 At the moment I am very busy printing something else, but wil reprint this one and make new pictures. Any suggestions until then are welcome. Thinking myself to change nozzle numbers to : .2 .3 .4 .5 .6 .8
15-5-2019 Uploaded a revision with the new numbering in place.
